Hi,

you can see it (mostly) here: [https://github.com/node-red/node-red/blob/master/packages/node\_modules/%40node-red/runtime/lib/nodes/index.js](https://github.com/node-red/node-red/blob/master/packages/node_modules/%40node-red/runtime/lib/nodes/index.js)

Here is `createNode`: [https://github.com/node-red/node-red/blob/f49d1ae8602c618f2e2e3707f3353389a3dd7dd8/packages/node\_modules/%40node-red/runtime/lib/nodes/index.js#L94](https://github.com/node-red/node-red/blob/f49d1ae8602c618f2e2e3707f3353389a3dd7dd8/packages/node_modules/%40node-red/runtime/lib/nodes/index.js#L94)

Did you have a particular question about the code?

Thank you knolleary. I didn't expect i will get such a detailed references.

I am looking for the code where the nodes are created based on the parameters (like, color, etc..)

If you are interested in creating a node and how it all fits together, perhaps this will help rather than examining this?

Actually i am interested to look at the code on how nodes are created and shown in UI based on the config. I am trying to do this in Angular so can take reference from this implementation. Please help me by pointing to the code
